Canadian satellite uplink for Boston network affiliates...

For quite a few years, Canadian satellite and cable television
systems have had a choice of US network affiliates which includes all
of the Boston big-four affiliates and WGBH, through an organization
called Cancom (Canadian Satellite Communications). As a Canadian
company, Cancom is not allowed to operate satellite ground stations in
the United States. US companies are not allowed up uplink to Canadian
satellites. So, at this facility, the Boston stations (all but two of
which transmit from the tower immediately overhead) are compressed and
uplinked to a US satellite, whence Cancom can receive them at a
receive site in Canada, where they can be remultiplexed with other
broadcast signals and uplinked to Canadian satellites. This facility
is operated by WGBH under contract to Cancom, to get around the
restrictions on foreign ownership.
